Bonnet switch

The bonnet switch is placed at the rear left of the engine bay. The switch is supplied with a pulse width-modulated (approx. 3.5%) voltage via a 1 k/ohm pull-up in TWICE. When the bonnet is opened, the switch is closed and the control module input is grounded.

TWICE uses the bonnet switch to trip the anti-theft alarm if the bonnet is opened when the alarm is armed.
